frox

A transparent FTP proxy for linux

It will transparently proxy your ftp clients (duh). This means that any clients you have that are behind the proxy will believe that they are connecting to an ftp server as normal, but will actually be connecting to frox. Frox will do the onward connection to the remote server. It can also be set up to do non-transparent proxying. In this case the ftp client can connect directly to frox, but instead of logging in with ``username'' should log in with ``username@ftp.wherever.org''. On either of these sorts of connections it can do caching of files you download, or converting of data connections from active-->passive which can make firewalling rules a lot easier/safer. There is also basic support for running a virus scanner on downloaded files. See <a href="http://frox.sourceforge.net/">http://frox.sourceforge.net/</a> for more information.
